Application July 6, 1934, Serial No. 733,950 1 Claim. (01. -117) The invention relates to an improvement in chairs. and particularly of the camp chair type wherein afiexible seat portion is provided.

It is one of the objects of the invention to provide an adjustable chair frame which can be moved to vary the position of the chair seat.

Another object of the invention is to provide a seat supporting portion for chairs which is made up'of three triangular positioned seat supports.

Another object of the invention is to support a chair seat at three spaced points so that the amount of sag in the seat may be adjusted.

.Another object of the invention is to provide an adjustable backfor camp chairs so that the position of the seat may be adjusted.

Another object'of the'invention is to provid extensible members for the arms of a camp chair so that a foot rest may be attached to such extension.

A still further object of the invention is to provide a fabric seat portion for camp chairs which may be lacedin position and adjusted to determine the amount of sag therein.

A still further object of the invention is to draw a fabric band about three spaced seat supports so that the seat portion will be spaced from one of the supports in order to provide a convenient and comfortable seat.

Other and further objects of the invention will be readily apparent when the following description is considered in connection with the accompanying drawing, wherein:

Fig. 1 is a perspective view of a chair constructed in accordance with the invention, and illusa trating the arms as extended to support the foot rest.

Fig. 2 is a section taken on the line 22 of Fig. 1.

Figs. 3 and 4 are plan views of the hardware used to adjust the back portion with respect to the legs.

The chair is preferably made up of two side frame portions indicated generally at 2 and 3. Each of these side frames is in turn made up of the legs 5 and 6 and the back member I l, the legs being pivoted at 1, so that they may be collapsed or folded when the chair is not in use. A pivot l 0 is provided on the upper end of the leg portion 5 and is arranged to receive the back member ll so that it may be adjusted with respect to the leg 5. To fix the back in any desired adjusted position the tongue [4 has been formed upon the bracket l5 which is attached to the lower end of the back piece II. On the leg 6 is a metal bar l8 which is provided with a plurality of openings l9, each of which is adaptedto receiveth tongue Id. In this manner by slightly raisingthe. back with respect to the leg, the tongue I4 may be moved into any one of the openings l9 sothat the back may be set at the desired angle. Suitable cross-connecting bars 20 are arranged between the legs so that they will serve as arigid support for the chair.

Attached to the upper end of the leg 5 is a hinge 22 by which the arm 23 is hinged to the upper end of the leg. Ahinge 25 isconnected to the upper end of the leg 6 and is of somewhat different construction than an ordinary hinge in that one side of the hinge is provided with a dovetailed slot 21 whichreceives'the dovetailed tongue 28 in sliding relationship; The tongue 28 is' formed on the lower side of the arm'i23 and'may be in the form of a metal strip attached to the arm. With this construction, the arm is connected to the top of the legs, but the legs can be folded because of the sliding connection of the hinge 25 with the arm. It is apparent that the arm 23 will remain substantially horizontal due to its connection toeach of the crossed legs. Each side frame 2 and 3 comprises legs 5 and 6, back members II, and the arms 23.

In order that the chair may afford an exceptional amount of comfort, the arms 23 are provided with thenextensions 30. Each extension is shown as having a tongue and groove connection as at 3| with the arm 23. In this manner the members may be extended 'to the position shown in Fig. 1 or they may be collapsed to the dotted line position shown at 32.

When these members 30 are extended they are arranged to receive the piece of fabric 34 which is in the form of a foot or leg rest and is shown as extending across from one arm to the other. This foot rest may be attached to the arms in any desired manner, but is here shown as constructed to provide the sockets 35 so that it can be telescoped over the arm members 30. If desired, this may be the only manner of supporting the foot rest, but if additional connection is desired and a continuous support for the legs is intended, then the tail-piece 31 may be constructed along with the foot rest.

This tail-piece is shown as looped about one of the cross bars 20 and may be fastened by suitable clasps or snaps 38. Thus when it is desired to use the foot rest the arm members 30 may be extended and the foot rest telescoped over them or otherwise attached, and if desired the tailpiece may then be snapped in position.

Particular attention is directed to the construction and arrangement of the seat 40. This seat is made up of a band or strip of flexible material such as canvas. This material is passed around the seat support members 4|, 42 and 43, and is drawn thereabouts by the cord or lacing 44. This cord is shown as having been laced through the ends of the seat band and passed about the support 42 so that any desired amount of sag may be had by adjustment of the cord 44. Any desired flexible connection may be used instead of the cord 44 if desired.

It should be noted that the seat supports 4|, 42 and 43 which also connect the side frames 2 and 3 are arranged in a triangular configuration with the longest side of the triangle between the supports 4| and 43 and with the support 42 out of alignment therewith. In this manner a flexible seat is provided in which any desired amount of sag may be obtained by adjustment of the cord 44 or by adjustment of the back members l by moving the tongues l4 into any one of the sockets IS. The positioning of the support 42 out of alignment with the supports 4| and 43 results in obtaining a strong seat support which is exceptionally comfortable, because there is no support interposed between the top and bottom of the fabric. It will be noted that when the back is tilted there will be relative movement of the supports 42 and 4| with respect to the support 43 so that the back may be adjusted if desired without any adjustment of the cord 44 and the amount of sag in the seat can be varied in this manner, but may be varied in addition by any desired adjustment of the cord 44.

The lacing arrangement of the canvas is of importance because the canvas may be readily removed for washing or replacement and any shrinkage or stretching of the fabric may be compensated for in an appropriate adjustment in the length of the cord, as distinguished from a canvas which is attached to fixed supports and cannot be adjusted. The position of the canvas on the supports can be altered by arranging the lacing either between the supports 4| and 42 or between the supports 42 and 43, or as shown in the drawing, can be so arranged that the lacing will be passed around the support 42. In this manner the wear on the canvas may be distributed by adjustment.

What is claimed is:

In a folding camp chair the combination of a frame, said frame being composed of two parallel connected side sections, each section comprising a pair of pivoted crossed legs, an arm member having an extention member thereon, said arm member being hinged to the upper end of one of said legs and slidably connected to the upper end of the other of said legs, and a back member pivoted adjacent the upper end of one of said legs; means to adjustably engage said back member with the other of said legs whereby the frame is maintained in open form, a plurality of connecting bars between said side sections, a support fabric, means to adjustably connect the ends of said fabric to form a continuous triangular loop about some of said bars to form a seat and back, one of said bars spacing one corner of the loop substantially away from the opposite side portion, and a foot rest having loops adapted to be slipped over the arm extension members whereby said foot rest forms a continuation of the seat.
